Characterization of CdSe Nanocrystals and their Interaction with Micellar Aggregates by Means of Capillary Electrophoretic Techniques

چکیده
Stable water soluble surfactant coated CdSe nanocrystals with trioctylphosphine (TOP) were obtained by a process of dynamic surface coating with cationic, anionic, and non-ionic surfactants. The surfactant-coated CdSe/TOP nanocrystals were characterized by complementary techniques of UV-VIS and photo-luminescence spectrophotometry, as well as by means of a capillary zone electrophoretic technique. The results revealed an integral relationship between the degree of change in photoluminescence and shift in migration in capillary electrophoresis for surfactant-coated CdSe/TOP nanocrystals. Therefore, the combination of electrophoresis and spectrophotometry can serve as valuable techniques for the measurement of such surface modifications on quantum dot nanocrystals.

Characterization of CdSe nanocrystals coated with amphiphiles. A capillary electrophoresis study
We have synthesized CdSe nanocrystals (NCs) possessing a trioctylphosphine surface passivation layer and modified with amphiphilic molecules to form a surface bilayer. The NCs covered with single amphiphiles are not stable in aqueous solution, but a mixed amphiphilic system is shown to provide stability in solution over several months. The solutions of the modified NCs were characterized by UV-...
